Abstract
Hybridization between different genotypes of Hordeum vulgare with different vegetative period due to their maturity was carried out in the study. Fertility of flowers during pollination was 21.7-63.1%. Vegetation period of parental forms was 190-214 days. Full dominance was observed in 18.75% and partial dominance in 25.4% of F1 Hordeum vulgare hybrids. 56.25% took an intermediate position. Hybrids of the F2 generation had a wide spectrum of fragmentation. In fast-growing hybrids with a relatively short vegetation period, the corresponding indicator was 3-12 days less than in both parental forms. This allowed it to be selected for practical use in selection lines with a relatively short vegetation period.
